Complex regional pain syndrome (CRPS) is a chronic pain condition that most often affects one limb (arm, leg, hand, or foot) usually after an injury. It is thought to be caused by damage to the nervous system.
WHAT IS GOING ON WITH THE NERVOUS SYSTEM WITH CRPS?
CRPS is thought to be caused by damage to the peripheral and central nervous systems. CRPS may also be caused by malfunction of these systems. The central nervous system is made up of the brain and spinal cord. The peripheral nervous system refers to the system that connects nerves from the central nervous system to the rest of the body.
WHAT ARE COMMON SYMPTOMS OF CRPS?
Prolonged or excessive pain and changes in skin color, temperature, and/or swelling in the affected area are the most common symptoms of Complex Regional Pain Syndrome. Some cases of the syndrome are mild, and severity of the conditions varies widely. In more severe cases, individuals may not recover and have long-term disability.
WHAT QUALIFIES AS CHRONIC?
Chronic pain conditions usually indicate that the pain has lasted than six months.
